After the dramatic rescue package for the euro area, the governing council of the European Central Bank decided to purchase European government bonds - to ensure an 'orderly monetary policy transmission mechanism'. Many observers argued that, by bond purchases, national fiscal policies could from now on dominate the common monetary policy. This note argues that they are quite right. The ECB has indeed become more dependent in political and financial terms. The ECB has decided to sterilise its bond purchases - compensating those purchases through sales of other bonds or money market instruments to keep the overall money supply unaffected. This is to counter accusations that the ECB is monetizing government debt. This note addresses how effective these sterilisation policies are.
